WASP-104b: NASA Shows ‘Pitch Black’ Planet Ever


New Delhi:  A ‘pitch black’ planet, darker than charcoal has been discovered. About 470 light-years away, it absorbs 99 per cent of light, making it one of the darkest planets ever found.

The planet was discovered by researchers from Keele University in the UK, who used NASA’s Kepler telescope to show that it is ‘darker than charcoal.’ The dark planet is named WASP-104b. ”This is one of the darkest planets ever discovered – reflecting very little light from its host star,” said Teo Mocnik from Keele’s Astrophysics Group, according to agency.

“WASP-104b is interesting because it was not even seen. All planets reflect starlight from their host star. Some planets are highly reflective, such as Venus reflecting 70 per cent of the light, while some others reflect only 10 per cent,” Mocnik said.

The dark planet was found orbiting a yellow dwarf star some 470 light-years away from us in the constellation Leo, and is categorised as a “hot Jupiter’ planet”.

Hot Jupiters are gas giant planets of a similar mass to Jupiter, but are located much closer to their host stars – making them very hot. WASP-104b is so close to its host star (at around 2.6 million miles) it takes just 1.76 days to complete its orbit.
